The immunological comparison of control PDA tumors and Krt19-edited PDA tumors


ABSTRACT: Our studies indicate that cancer cells of carcinomas are coated with CXCL12 chemokine in covalent conjugation with keratin-19 (KRT19). Murine pancreatic ductal adenocarcinomas (PDA) formed with Krt19-edited cancer cells lack the CXCL12-coating and are infiltrated with T cells, compared to tumors formed with control sgScramble PDA cells. To probe the immunological role of this CXCL12-coating thoroughly, bulk RNA sequencing of subcutaneous (s/c) murine sgScramble PDA tumors and Krt19-edited PDA tumors were conducted. As comparison, an immunogenic tumor model was also assessed. To do so, s/c sgScramble PDA tumors and PDA tumors formed with sgScramble cells exppressing doxcycline-inducible ovalbumin (icOVA) were harvested and processed for bulk RNA sequencing.
